TO THE SHOE HARD- WARE COMPANY, OF WATEBBUBY, CONNECTICUT, A CORPORATION OF CONNECTICUT rasrnnmo DEVICE Application filed July 2, 1924. Serial No. 728,629.

This invention relates to fastening devices,

more particularly a multiple fastener engageable or disengageable by operation of a slider. It aims to provide a new and improved type of multiple fastener for plackets or openings, one that is-re'liable in service,

simple and rapidly operable, and comparatively easy to manufacture at a low cost of sheet metal.

With the illustrated embodiment in mind, and without any intention to limit more than is required by the scope of the prior art,the

' invention briefly stated consists in a-seriesof inter-engageable elements provided with hooks and eyes which are adapted to be connected together or'disconnected by operation of a slider tracking the elements or members which are secured within the respective mar gins of the placket or opening.

Embodiments of the invention are illustrated in the drawings, in which Figure 1 is a plan view of a pair of stringers partly secured together with one form of elements of the present invention; and partly separated, a closing slider being also shown.

Figure 2 is a section through the narrow end of a closing slider in working relation with a pair of fastening elements;

Figure 4 is a plan view of a slightly modified arrangement of the same elements;

The invention may be embodied in metal or various other materials. The fastening ele-' ments or interengageable members may be variously arranged to meet requirements.

In the drawings, Figures 1-3, is shown a form of invention in which each inter-ena stringer, 5 preferably but not necessarily consisting of fabric cut on the square or bias folded around a cord, wire, or other form of piping 6 to afl'orda good clamp or anchorage. The inter-engageable members may be and preferably are made of sheet metal folded and crimped as 'clearl shown in cross section in Figure 2. 'Pre erably they are at tached to the stringers opposite each other with the hooks 2 all on one side of the lacket and the eyes 3 on the other side t ereof.

Variantly, as shown in Figure 4, the hooks and eyes may be arranged in alternation on both sides of the placket or opening in the shoe,vgarment, tent,'box, or other article to portions 1B of this form of multiple fastener the- 1piping 6B is housed as in Fi ure 5, and

e eyes 313 int e barrel portions in which t are provided the plies of the stringer are caught and clinched by the metal turned and folded back as indicated at X from the body of the barrel to form the eye.

' All forms of the inter-engageable members, however, comprise element-carryingportions 11A--1B and stringer-gripping portions 4 4A4B, the latter being minimized in width in all or half of the members if it is desired to decrease the width of metal visible. External grooves 7 7A-7 B are provided on opposite sides of the members,

the grooves being defined by outer and inner walls substantially coextensive with the length of each member, said grooves flanking the element carrying portions 1-1A1B for the reception of curved flanges 8 in opposed pairs projecting inwardly from plates 9 pinned to a spacing block 10 and together therewith constituting a slider 11. The slider 11 successively engages or disengages the hooks 2 and eyes 3 in a manner obvious from -the drawings. A ring 12 fixed as shown to cylindrical barrel portions 1 of the interengageable members as shown in Figure 3 of the drawings of a length adapted to maintain the series of elements in alignment and more or less coplanar with the flexible'stringers 5, each projection fitting loosely into the bore of the adjacent barrel portion so as not to permit movement of the members in arcuate or curved paths in passing through the operating slider.

It is to be noticed that the interengageable members are arranged directly opposite one another, that the elements are grooved externally so as to insure reliable operation of the slider whose flanges track the substantially. continuous metallic guideway thereby provided, that the elements are constructed out of sheet metal in one piece, that the complete fastener is practically proof against disarrangement or jamming in service, that the assemblage presents a symmetrical and attractive appearance, and that the hooks are struck from the body of the elements and lie in the plane of the fastener-elements in a manner utilizing the strength of the metal to the best advantage. The hooks 2 are flat and parallel with the stringers 5. The shank portions of the hooks 2 are of a width substantially equal to the length of the eyes 3 which they approximately fill at least in the direction of extent of the inter-engaged members. It will be noticed that the curved hook is -wider at its junction with the body member engaged by direct lateral pull upon the opposite stringers or otherwise than by operation of the slider. The hooks 2 are integral with the body of the members 1, having been struck therefrom and folded through an angle of more than 90, the line of fold or juncture between the hooks and the body extending in the direction of the length of the members 1. The hooks 2 are thus ruggedly constructed in one piece with the body of the I claim and desire to protect by Letters Patent is:
